Medical Xpress / Blocking immune 'signal two' expands gut tolerance cells, may open new IBD treatments
Weill Cornell Medicine investigators made an unexpected finding about how the immune system normally suppresses inappropriate chronic inflammation in the intestine, potentially opening new avenues for therapies against inflammatory ...
Phys.org / The fake disease that fooled the internet, and what it says about all of us
Until a few years ago, no one had heard of bixonimania. Then, in 2024, a group of scientists posted findings online announcing the condition, which they claimed affected the eyes after computer use. However, the scientists ...
Phys.org / The threat of light pollution puts the world's darkest skies in the Atacama Desert at risk
It takes a moment for the eyes to adjust. A faint spark appears in the darkness; then another, brighter one. Soon, stars, planets and entire constellations emerge. Before long, a whole galaxy stretches across the sky, visible ...
Science X / Alien comet carries record-heavy water, and its birthplace looks nothing like our cosmic neighborhood
Less than a year ago, astronomers discovered a comet soaring through our sky that was not from our solar system. Although we still don't know where this interstellar object called 3I/ATLAS came from, research led by the University ...
Phys.org / More activity means less response in active materials
For some time, researchers have assumed that solid materials could gain more useful properties by making their microscopic components more active. Now, a team led by Jack Binysh at the University of Amsterdam has found that ...
Medical Xpress / Antibodies can selectively shut down harmful T cells without weakening whole immune system
The immune system is the frontline protection against infection, continually searching for and destroying unknown pathogens. While typical operation of the immune system scans for threats, some systems attack the body's own ...
Tech Xplore / Battery-free textile turns clothing into a real-time blood pressure monitor
Over the past decades, technological advances have opened remarkable possibilities for the detection and monitoring of various physiological signals associated with heart health (e.g., heart rate and ECG), sleep stages and ...
Phys.org / Extreme stability in ultrafast nanomagnetism aids the development of faster data storage
For the first time, researchers have mapped how the boundaries of magnetic nanostructures behave on extremely short timescales. The work of physicist Johan Mentink of Radboud University shows that these boundaries are much ...
Tech Xplore / This artificial retina doesn't just aim to restore sight—it opens a hidden channel of vision
The retina, the thin layer of tissue at the back of the eye, is made up of photoreceptor cells that convert visible light into electrical signals, which is essential for human vision. Some diseases, such as retinal degeneration, ...
Medical Xpress / After assault, OCD risk rises fastest in first year, pointing to a critical care window
Obsessive compulsive disorder (OCD) is a mental health condition characterized by recurring intrusive thoughts (i.e., obsessions) and repetitive behaviors (i.e., compulsions) aimed at reducing anxiety. This disorder is estimated ...
Phys.org / Chernobyl's wildlife: The real story isn't the presence of radiation, it's the absence of humans
"Dogs at Chernobyl are now genetically distinct … thanks to years of exposure to ionizing radiation, study finds."
Phys.org / Carbon nanotubes are closing the gap on copper conductivity
Carbon nanotubes are one technology that many observers believe hasn't quite lived up to the extreme hype that surrounded them when they first appeared on the scene in the late 1990s. At that time, much was made of their ...
